how can I get get the hexadecimal value of the char insert in a edit control
(every time I press a key I want an alert message of its hexadecimal value)
mmmm.. if you are talking about unicode key value, you can use:
onkeydown="alert(event.keyCode)"
this will give you a decimal unicode number representing the character
(just take a look at an ascii table to obtain all codes..)
As far as i know it does not make any distinction about lower and up
case (a and A returns 65)
event.shiftKey will tell you if shift key is pressed.
Converting to an hex value is up to you (google is you friend)
